Dual-Cell Patch-Clamp Recording Revealed a Mechanism for a Ribbon Synapse to Process Both Digital and Analog Inputs and Outputs

open access: yesFrontiers in Cellular Neuroscience, 2021
A chemical synapse is either an action potential (AP) synapse or a graded potential (GP) synapse but not both. This study investigated how signals passed the glutamatergic synapse between the rod photoreceptor and its postsynaptic hyperpolarizing bipolar

Phosphoinositides and Photoreceptors [PDF]

open access: yesMolecular Neurobiology, 2011
The importance of phosphoinositides (phosphorylated phosphatidyl inositol derivatives, PIs) for normal cellular function cannot be overstated. Although they represent a small fraction of the total phospholipid within the cell, they are essential regulators of many cellular functions.

Mouse rods signal through gap junctions with cones

open access: yeseLife, 2014
Rod and cone photoreceptors are coupled by gap junctions (GJs), relatively large channels able to mediate both electrical and molecular communication. Despite their critical location in our visual system and evidence that they are dynamically gated for ...

The photoreceptor mosaic [PDF]

open access: yesEye, 1998
The organisation of the human photoreceptor mosaic reflects evolutionary strategies for optimising visual information under a wide range of stimulus conditions: (1) The rod population dominates (max. 170,000/mm2 at c. 30 degrees sup.) except for the central 2 degrees and along the ora serrata.

The Vitamin B12-Dependent Photoreceptor AerR Relieves Photosystem Gene Repression by Extending the Interaction of CrtJ with Photosystem Promoters

open access: yesmBio, 2017
Purple nonsulfur bacteria adapt their physiology to a wide variety of environmental conditions often through the control of transcription. One of the main transcription factors involved in controlling expression of the Rhodobacter capsulatus photosystem ...

Ganglion cell complex thickness in screening of hydroxychloroquine maculopathy

open access: yesDelta Journal of Ophthalmology, 2020
Background Screening of early hydroxychloroquine (HCQ) maculopathy is important to prevent permanent structural and functional retinal damage. Spectral domain optical coherence tomography (SD-OCT) ultra-high-resolution imaging and speed allows better ...

Targeting the HDAC6‐Cilium Axis Ameliorates the Pathological Changes Associated with Retinopathy of Prematurity

open access: yesAdvanced Science, 2022
Retinopathy of prematurity (ROP) is one of the leading causes of childhood visual impairment and blindness. However, there are still very few effective pharmacological interventions for ROP.

Cholesterol homeostasis in the vertebrate retina: biology and pathobiology

open access: yesJournal of Lipid Research, 2021
: Cholesterol is a quantitatively and biologically significant constituent of all mammalian cell membrane, including those that comprise the retina. Retinal cholesterol homeostasis entails the interplay between de novo synthesis, uptake, intraretinal ...

Loss of Motor Protein MYO1C Causes Rhodopsin Mislocalization and Results in Impaired Visual Function

open access: yesCells, 2021
Unconventional myosins, linked to deafness, are also proposed to play a role in retinal cell physiology. However, their direct role in photoreceptor function remains unclear.

UV Radiation Induces Specific Changes in the Carotenoid Profile of Arabidopsis thaliana

open access: yesBiomolecules, 2022
UV-B and UV-A radiation are natural components of solar radiation that can cause plant stress, as well as induce a range of acclimatory responses mediated by photoreceptors.
